Bark , root , leaves , fruit and latex of this plant are frequently usedfor the treatment of various illnesses. Ficus produces a unique fruit which is actually a inverted flower. Ficus species are rich source of polyphenolic compounds , flavanoids which are responsible for strong antioxidant properties that help in prevention and therapy of various oxidative stress related diseases such as neurodegenerative and hepatic diseases. The present review correlates antioxidant activity of Ficus species with its pharmacological activities. Key words : Ficus species, Free radicals, Polyphenols , flavanoids , Antioxidant property. Introduction Genus : Ficus Ficus, the fig genus, consists of over 800 species and is one of about 40 genera of the mulberryfamily. The Various species of Ficus are [2]– fig species of greatest commercial importance is Ficus Ficus altissima (council tree) carica L. (the common fig).

Low along with anti platelet activity. Hence, it can be used levels of antioxidants or inhibition of the antioxidant in gut motility and inflammatory disorders [18]. enzymes, cause oxidative stress and may damage or kill the living cells. Oxidative stress and role of antioxidants As oxidative stress is an important part of many Oxidation refers to transfer of electrons from a human diseases, the use of antioxidants in substance to an oxidizing agent. Oxidation reactions pharmacology is intensively studied, particularly in results in free radicals ,which immediately start chain the treatment of stroke and neurodegenerative reactions that result in damage to the living cells [19]. diseases.Antioxidants are widely used as ingredients Metabolism in majority of complex living organisms in the dietary supplements in order to maintain health requires oxygen for its survival .But, oxygen being, a and to prevent diseases such as cancer and coronary highly reactive molecule damages living organisms by heart disease [27]. producing reactive oxygen species [20] . These These compounds may be synthesized in the body or reactive oxygen species produced in the living cells obtained from the diet [28].The different antioxidants include hydrogen peroxide (H2O2 ) , hypochlorous are present at a wide range of concentrations in body acid (HOCl) and free
